Powering the future: How the DOE is fueling nuclear fuel cycle research and development
As global interest in nuclear energy surges, the United States must remain at the forefront of research and development to ensure national energy security, advance nuclear technologies, and promote international cooperation on safety and nonproliferation. A crucial step in achieving this is analyzing how funding and resources are allocated to better understand how to direct future research and development. The Department of Energy has spearheaded this effort by funding hundreds of research projects across the country through the Nuclear Energy University Program (NEUP). This initiative has empowered dozens of universities to collaborate toward a nuclear-friendly future.

The simplified P2 (SP2) approximation to the transport equation is derived by a formal procedure and by a variational analysis. The variational analysis yields the SP2 equations, together with interface and Marshak-like boundary conditions. Numerical calculations show that the resulting SP2 solution is generally more accurate than the P1 solution for both integral quantities and detailed flux distributions, except near material interfaces, where the SP2 solution is discontinuous.
